Scott Harn was after me to write for the ICMJ Prospecting & Mining Journal for ages, and both JP and Chris Ralph told me I should get hooked up with the Minelab Treasure Talk blog. Leaving my day job seems to have motivated me because somehow the bills never stop. So I have been pretty consistent with getting articles to Scott and finally got around to getting on Treasure Talk. See my new intro at http://www.minelab.com/emea/treasure-talk/say-hello-to-the-newest-member-of-our-expert-treasure-talk-team Now I just need to write up something of interest! Hopefully you will see my first entry in the next few weeks.

Start at https://www.detectorprospector.com/magazine/steves-guides/metal-detecting-and-prospecting-library/ Especially these two: How Metal Detectors Work by Mark Rowan & William Lahr - Originally published by White's Electronics as a booklet P/N 621-0395. Basic but rather technical information on how induction balance and pulse induction metal detectors work. Metal Detector Basics and Theory by Bruce Candy - Bruce is a co-founder of Minelab and the man behind their most advanced designs. This information delves into much greater detail than the above link and has many more illustrations and diagrams. Before Carl Moreland was Engineering Manager at White's Electronics (and now First Texas), he created a website that has more technical information on metal detectors than any I know of. The Geotech website has lots of interesting stuff and in particular it has a lot of "build your own" metal detector projects for the electronically minded. I have never done this myself but if you were ever curious about what makes detectors tick a lot can be learned here. Projects http://www.geotech1.com/cgi-bin/pages/common/index.pl?page=metdet&file=projects.dat Info http://www.geotech1.com/cgi-bin/pages/common/index.pl?page=metdet&file=info.dat George Overton & Carl Moreland, co-admins for the Geotech web site, also wrote the new book, Inside the Metal Detector. This is not another "how to use a metal detector" but rather a look inside to the operating principles and electronics that make a detector work. Inside the Metal Detector explains theory and offers numerous experiments and projects that demonstrate the theory. You can build an off-resonance pinpointer, a GEB-discriminator, and a microprocessor-controlled PI detector. Even if you're not inclined to build a detector, the concepts learned from ITMD will help you better understand how your own detector works and what all those controls are really doing. The book can be purchased in paperback or Kindle versions on Amazon

For more detail, Carl Moreland has book that he has written.

There is a wealth of info on Steve's main website

Yup, I have done it many times. Just one example a couple years ago, I picked 98 small nuggets of a hillside 75 feet above a creek with a Gold Bug 2. I should have dug two more - would have if I had known I was that near 100! Anyway, we set Chris and George up there with a highbanker and they got around three ounces of gold from the location.
